Definition
Pseudo-black chaff or melanism. False black chaff is a physiological condition resulting from a deposition of melaniod pigments and is completely associated with the presence of the stem rust resistance gene Sr2. Symptoms include brown to black discoloration of the glume extending from slight longitudinal marks to large black areas covering most of the glume surface. In severe expression, the stem area below the last node may become distinctly brown to black discoloured. The trait appears post-flowering with a peak at late milk-soft dough stage.
